COSMOS use at the Southern Sierra Critical Zone Observatory
3rd Annual COSMOS Workshop

CZO Common Infrastructure
With the goal to:• resolve the evolution and formation of the CZ
and its attributes• measure the properties and structure of the
present-day CZ• construct carbon, mass and energy balances
(event- to long-time scales)Energy
Southern Sierra CZO
Southern Sierra Critical Zone Observatory (CZO) soil moisture measurements:
• cosmic-ray• time domain reflectometry (TDR)• dielectric• neutron probe• physical sampling techniques.
Installation and Survey
Hiking the COSMOS sensor into P301.
Volumetric Water Content

Effective soil depth
Snow depth
Snow depth variability
Dealing with snow
Soil water estimates, 0-30 cm
Correlation of COSMOS VWC
with distributed sensor network during no-snow
conditions
The Future
• Easy to deploy– Elevations, aspects, sets of sensors
• Soil moisture and vegetation– Timing of moisture stress– Evapotranspiration
• Snow and/or snow+soil storage

Common CZO Infrastructure
• Fluxes within and across the critical zone boundaries– vegetation-atmospheric– terrestrial-aquatic– soil-atmospheric– soil-plant– bedrock-soil
